Perhaps more surprising, the experimental group experienced broad improvements in their psychological well-being, including fewer hallucinations, less emotional withdrawal, and less somatization, meaning the manifestation of psychological distress in physical symptoms.

In fact, "the study results reflected a negative correlation between the residents 'exposure to the Wall and psychological symptoms; among the adult group (feeling lonely and somatization); among adolescents and children, positive correlation between exposure to the Wall and psychological symptoms (agitation, verbal violence, nightmares, and concentration problems)."

(FOOTNOTE 8) That the frequently expressed belief in 'somatization disorder' and other mental disorders has been applied to ME/CFS by the psychiatrists involved in the PACE Trial, there is indeed a very clear assumption of an "original cause of illness", contrary to White et al's claims in their letter to the Independent.
